Plaster-Holding Net Roller Measurement for Compact Vertical Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for measuring and cutting plaster-holding nets require a significant amount of space and are inconvenient, often leading to discomfort and potential injuries for operators due to the need to perform operations on the ground, with limited precision.
Innovation Solution
A measuring device comprising a frame, rollers, locking means, acquisition means, and processing means that allow the net to be measured and potentially cut within a confined space, avoiding the need to bend down and ensuring precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the net is fully extended on the ground for measurement and cutting, then the measurement can be performed, but a considerable amount of space is required
Solution Approach 1:
The invention transitions the measurement operation from a two-dimensional ground-based layout to a three-dimensional vertical configuration. The net is wound around a roller and measured vertically through a guide pulley system, allowing the measurement to occur in the vertical dimension rather than requiring horizontal space on the ground.
Solution Approach 2:
The invention introduces a roller and guide pulley as intermediary elements between the net and the measurement system. These intermediaries allow the net to be handled vertically and guide it through a compact measuring mechanism, eliminating the need for the net to be fully extended on the ground.
2Ease of operation
If the measurement and cutting operations are performed on the ground, then the operations can be carried out, but discomfort and injuries may occur for operators
Solution Approach 1:
The invention moves the measurement and cutting operations from the horizontal ground plane to a vertical configuration. The net is handled through a guide pulley system that allows operators to work standing upright, eliminating the need to bend down or kneel on the ground during measurement and cutting operations.
3Measurement precision
If the net is measured using manual instruments on the ground, then the measurement can be performed, but precision may be compromised
Solution Approach 1:
The invention replaces traditional manual measuring instruments with a mechanical measurement system based on the roller and guide pulley mechanism. The measurement is performed through the rotation of the roller and the corresponding movement of the net, providing more consistent and precise measurements while maintaining operational ease.

AI summary
A measuring device (1) for a plaster-holding net is provided, comprising a plaster-holding net (10), a frame (2), a first roller (3) extending along a main axis (3a), loosely constrained to the frame (2) in such a way as to be able to rotate around the main axis (3a) with respect to the frame (2) and supporting the plaster-holding net (10) rolled thereon, and a second roller (4) extending along a secondary axis (4a) parallel to the main axis (3a), loosely constrained to the frame (2) so as to be able to rotate around the secondary axis (4a) with respect to the frame (2); the device further comprises locking means (5) configured to lock an end of the plaster-holding net (10) onto the second roller (4) and to allow the second roller (4) to wrap the plaster-holding net (10) around itself when rotated about the secondary axis (4a) and to unwind the plaster-holding net (10) from the first roller (3); it also includes acquisition means (6) configured to detect a rotation angle of the plaster-holding net (10) on the first roller (3), and processing means (7) operatively connected to the acquisition means (6) and configured to determine the length, perpendicular to the secondary axis (4a), of the plaster-holding net (10) wound around the second roller (4) in relation to the rotation angle and with respect to a predetermined reference integral with the frame (2).
